	 * 新增：/order POST
	 * 删除：/order/1 DELETE   delete?id=1
	 * 修改：/order/2 PUT   	 update?id=2
	 * 查询：/order/3 GET      get?id=3
	 * 
	 * 如何发送PUT请求和DELETE请求
	 * 1.配置HiddenHttpMethodFilter
	 * 2.发送post请求
	 * 3.form发送post请求是，添加隐藏域name="_method",值为DELETE或PUT
	 * 
	 * 在springmvc的目标方法中可以通过@PathVariable注解得到id值
